Tylo timeouts

I’m not sure what is wrong with tylo right now. It has >300 tests timing out after getting this:

ERROR: In C:\dashboards\buildbot\2000d565\source\VTK\Rendering\OpenGL2\vtkShaderProgram.cxx, line 491
vtkShaderProgram (0000000016FCD9F0): Shader object was not initialized, cannot attach it.

just to be sure, no VRAM or RAM leak here ?

Not as far as I could tell from the nvidia settings application. These started immediately after rebooting it without any builds being good first, so it isn’t behaving like the VRAM leaks on vall either.

Tylo is now totally green on master (except one warning from VTK)

Let’s try to keep it that way :).

It was actually caused by a bug in QVTKOpenGLWindow, corrected by @martink a few days ago.
